Sanjay Vijay Manjrekar (born 12 July 1965) is an Indian cricket commentator and former cricketer. He played international cricket for India from 1987 until 1996 as a right-handed middle-order batsman.

Manjrekar was born in Mangalore, in what was previously known as Mysore State (present-day Karnataka) in southern India in a Marathi family, on 12 July 1965, the son of Vijay Manjrekar, who made 55 Test match appearances for India between 1952 and 1965. As a schoolboy, he competed in the Cooch Behar Trophy between 1978 and 1982. He attended Bombay University, and played in the Vizzy Trophy and the Rohinton Baria Trophy between 1983 and 1985, winning both in 1985, with West Zone Universities and Bombay University respectively.

Manjrekar made his first-class cricket debut on 7 March 1985, scoring 57 runs in his only innings for Bombay during their Ranji Trophy quarter-final victory over Haryana. He retained his place in the semi-final but did not play again after that until the following season. He performed steadily in 1985–86, averaging 42.40 with the bat, though his highest score was 51 not out. The following season, he struck his first century in first-class cricket, remaining 100 not out during the first innings of a match against Baroda.

Domestically, he enjoyed success in the 1990–91 season, scoring four centuries and one half-century in eight first-class appearances. During the season, he scored his highest total, 377, in the Ranji Trophy semi-final against Hyderabad.

He won a second Ranji Trophy final in 1996–97, captaining his team, by this stage renamed Mumbai. Manjrekar scored 78 runs in the match, in which both sides only batted one inning.

In late 1987, Manjrekar made his international debut, facing the West Indies in Delhi. He scored five runs in the first innings and ten in the second when he retired hurt. His first half-century in international cricket was made against New Zealand in December 1988, during a Day International. Manjrekar scored 52 runs during a narrow victory for India. The following April, he scored his maiden Test cricket century, hitting 108 against the West Indies. He scored his second Test century in November 1989, against Pakistan. In the fourth innings of the match, he scored 113 not out to help India draw the match. In the third Test of the same series, Manjrekar made his highest score in Test cricket, reaching 218 runs in the first innings, before being run out. He did not score another international century for two years when he hit 105 runs from 82 balls in an ODI against South Africa.

Manjrekar scored his final international century against Zimbabwe, in October 1992, reaching 104 in a drawn Test match.

After retiring from professional cricket, Manjrekar began working as a cricket commentator.
